Generalized Linear Inversion Using Tau-P Forward Modeling, Stephen Dade Walker

Graduate Theses

The Generalized Linear Inversion (GLI) method is used in conjunction with a tau-p forward model to successfully perform inversions of test and real-data examples. All data examples used are one-dimensional velocity profiles that represent several different cases. The stability of the technique is demonstrated in all the test-data sets. The use of simple models and wel1-control 1ed test data results in a minimum of iterations of the inversion process. Different levels of perturbation of the model and test-data examples are used to reveal insight into the robust nature of the inversion.

Statistical Analysis Of A Compound Power-Law Model For Repairable Systems, Max Engelhardt, Lee J. Bain

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Conclusions - A compound (mixed) Poisson distribution is sometimes used as an alternative to the Poisson distribution for count data. Such a compound distribution, which has a negative binomial form, occurs when the population consists of Poisson distributed individuals, but with intensities which have a gamma distribution. A similar situation can occur with a repairable system when failure intensities of each system are different. A more general situation is considered where the system failures are distributed according to nonhomogeneous Poisson processes having Power Law intensity functions with gamma distributed intensity parameter. If the failures of each system in a population …

The Mechanical Properties Of The Bonne Terre Formation Dolostone According To Carbonate Facies And Moisture Conditions, Sweetwater Mine, Viburnum Trend, Southeast Missouri, Harvey Edwin Goodman

Masters Theses

"The mechanical properties of the Bonneterre Formation dolostone are critical to the design of underground mine openings at Ozark Lead Company's Sweetwater Mine, southeast Missouri. Host rock strength and elastic moduli, as affected by carbonate facies and varying moisture conditions, can influence rock stability in this multi-horizon mine.

Lead and zinc sulfide ores occur throughout the 350 foot-thick Bonneterre formation found in the mining area. Orebodies are mined in all four carbonate facies of the Bonneterre, including the (1) micrite (mudstone/wackestone) and shale facies, (2) the oolitic (packstone/ grainstone) facies, (3) the digitate stromatolite (boundstone) facies, and (4) the planar …

Site Characterization Of Riverfront Park, Kansas City, Missouri, For The Purpose Of Hazardous Waste Site Remediation, Helen Hudson Scannell

Masters Theses

"Riverfront Park, Kansas City, Missouri is located on a point bar along the Missouri River. Portions of the site have historically been used (1950 - 1973) as a municipal landfill receiving residential, commercial and industrial wastes. Relatively high concentrations of elemental lead have been found in small areas of the surface soil within the limits of the Park. Chemicals that may be present in the landfill wastes create a potential for groundwater contamination. A Remedial Investigation, including a series of groundwater monitoring wells is necessary to characterize groundwater geochemistry and flood-induced changes in groundwater flow direction, and to assess any …
